SPECIFICATION forming' part Of Letters Patent NO. 703,730, dated July 1,1902.

Application filed October 6, 1900. Serial No. 32,263. (No model.)

To a/ZZ whom, it may concern:

Beit known that I, PAUL LADEwIG, Ph. a citizen of the Empire of Germany,residing at Essen-on-the-Ruhr, in the Empire of Germany, have inventedcertain new and useful Improvements in Temporary Binders, of'

which thel following is a specification. j j

This invention relates to improved temporary binders of that class whichis intended to temporarily bind newspapers, periodicals, doc., in aquick and convenient manner until the'volume is completed, so that thelnumbers can iinally be bound. f i

The invention consists of a temporary binder comprising posts securedtothe backI of the binder, locking devices passing through the frontofthe binder into the postsand interlocking therewith,and perforated orlooped connecting -pieces placed on the posts and provided with hingedwire staples, that are attached through the papers or periodicals to beiiled.

The invention consists, further, of the perforated or looped connectingpiece with a U-shaped -wire staple hingeditojone edge of the same, aswill be fully described hereinafter. l

In the accompanying drawings, Figure l represents a perspective view ofmy improved temporary binder, showing a periodical applied to the same.Fig. 2 is also a perspective View showingthebinder in the actof having aperiodical inserted into the same. Figs. 3 and llare enlarged transversesections showing the connecting posts on the back and front of thebinder, being, respectively, a sideV elevation of the fastening andaicentral section thereof.

back cover, and B-thefront cover, of my iin-A provedv temporary binder,and C is a backv for the same, which is connected by flexible hingeswith the front and back covers V`and'i's formed of three strips orpieces C C2 O3, that Fig. 5 is a detail; plan view of y'theconnecting-piece with its hinged wire are also connected by flexiblehinges, so as to be placed either ilat, as shown in Fig. 2, or formedinto a U-shaped back, as shown in Fig. l.

The strip C3 of the back C, adjacent to the rear coverA, is provid edwith screw-threaded hollow posts D D', which are connected therewith b vscrews d, the heads of the connecting-screws d being nicked, so as toscrew the same into` the strip C3 of the back. The posts D D/ are madetubular, two or more being provided, according io the size of thetemporary binder, and at the upper end post D, as

shown, or both, is provided with an L-shaped recess d", Which receives apin c, projecting from a removable headed pin E, that is inserted withinan opening e in the front strip C2 of the back C, said opening beingrein- -l`orced by a perforated .sheet-metal eyelet eX,

provided with a recess e2 for permitting the insertion of the smallprojecting pin e of the main pin E, so that the same can be readilypassed through the opening e' into the post D and guided along therecess d until it arrives at the lower transverse portion of the same. Abayonet-joint connection is thus formed. The main pin E is then turned,by means of a suitable key inserted in recesses or holes in its head,sothat the projecting pin e interlocks with the transverse portion ofthe recess d', and thereby looks the front cover to the back cover, asshown in Figs. 2S and 4. j`

A helical spring f is introduced between `thevfastening-screw ol of thepost Dwand the inner end of theniain pin'E,"as shown in Fig. 4, so thata certain tension is' 'exerted on the locking-pin` E, and thereby theaccidental loosening, turning, or detachin'g of the pin from the postprevented... i

For connecting the periodicals, newspapers, dto., to be` temporarilybound with the binder a connecting-piece is used, which consists of aperforated metal plate g, provided Witha hinged wire 'staple'g' at, one.edge, as shown in Fig. 5.

In place of the perforated metallic cpnlnecting-plate g a perforatedstrip g2 of stout paper, preferably one doubled up, asin Fig. 6, or awire loop g4, as shown in Fig. Y7, may be used, said connecting-stripbeing preferably as long as the periodical to IOO l be bound and thewire staple in all forms of the connection being passed through thefolding edge of the periodical into the inside of the same, where theends of the staple are clenched, so that they retain the newspaper,periodical, thc., in the binder.

My improved temporary binder is used as follows: The paper to be filedis lirst connected with the connecting-piecegor strip g2 or loop g4 bypassing the ends of the staples through the folding edge of the same,after which the ends are clenched over. The binder is then opened byturning the interlocking-pin E by means ofthe key. When severalconnecting-posts are used, one pin E after the other is released bymeans of the key, the spring in the interior of the post pushingr themain pin upward as soon as the small interlocking-pin e is in thelongitudinal portion of the recess in the post, so that the lockingpinscan be conveniently detached and the front cover moved away from theback cover, as shown in Fig. 2. The perforated metallic pieces g orstrips g2 or loops g4 are then placed over the posts D Dand the frontcover placed back over the back cover, so that small pins e on the mainpins Ecan beinterlocked,by means ofthe key, with the recesses d' of theposts D, as shown in Fig. l. On turning the interlocking pins E with thekey the interlocking of the small projecting pin e with the transverseportion of the recess d is accomplished, as before described. Thenewspaper or periodical is then in the proper position in the binder,after which the binder is placed on the table or any other place foruse.

In the drawings a temporary binder is shown in which only onelocking-pin E is used, the second post D' not being provided with alocking-pin, but with a rounded-off end, which engages into a depressionor socket s, set into the front strip C2 of the back C, as shown in Fig.2. This requires the unlocking of only one locking-pin when opening orclosing the binder. This arrangement is well adapted for small temporarybinders. For larger binders, however, it is preferable to have two ormore pins, asr thereby better stability is given to the binder and morereliable connection between the front and back covers is obtained.

The perforated connecting plates or strips or loops with wire stapleshinged to their edges are made and supplied in quantities, so as to bealways ready for use by the parties using the binders. The staples g areapplied to the metallic plates g by a hinge-sleeve g3, placed around themiddle portion of the staple, and to the loops g4 by means of eyes g5,while when connecting paper strips are used the ends of the wire staplesarc pierced through the folded edge ofthe strip, as shown in Fig. 6.

The advantage of my improved temporary binder is the convenience in use,so that newspapers, periodicals, sheet-music, or other articles to bebound can be readily collected in the same until a suiicient number iscollected, when they are removed from the temporary binder by openingthe connectingposts and locking-pins, removing the connecting-piecesfrom the posts, and then removing the Wire staples from the folded backof the periodicals by opening the staples, when the papers are ready forbinding.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is

l. A temporary binder, consisting of two covers, a back with hingedconnection therewith, and having-openings, posts attached to a portionof the back, o e of said posts being hollow and provided wit an L-shapedrecess at its open end, a headed locking-post passing through one ofsaid openings in another portion of the back, and provided with alateral pin for interlocking with the L-shaped recess of the hollowpost, and an eyelet provided in said opening and having a recess thereinfor the passage of said lateral pin, substantially as set forth.

2. A temporary binder, consisting of two covers, a back hinged to thecovers, and composed of a middle and two side strips hinged together, atubular post projecting from one ofsaid side strips, and having aninteriorlythreaded lower end, a headed screw for attaching said post tosaid strip, an L-shaped recess in the opposite end of the post,locking-post passing through the other side strip of the back andprovided with a projecting pin interlocking with the L-shaped recess ofthe tubular post, and a tension-spring interposed between thefastening-screw of the tubular post and the inner end of thelocking-post, substantially as set forth.

Atemporary binder, composed ofcovers, a three-part back to which theyare hinged, openings in one of said parts, posts, one of which connectsthe front and rear strips of said back, the other of said parts guidedin one of said openings, and connecting-pieces adapted to be placed onsaid posts and provided with hinged wire staples for connection ofnewspapers, periodicals, the., substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

PAUL LADEWIG.
